Costco has taken legal action against the Trump administration, asking the Court of International Trade to review the legality of tariffs imposed under the International Emergency Economic Powers Act (IEEPA). The company claims these tariffs are unlawful and is seeking a refund for all duties paid because of President Trump’s executive order.
Costco’s argument is centered on the idea that the IEEPA doesn’t give the President the authority to set tariffs on imports. This lawsuit follows a bigger conversation in the Supreme Court regarding Trump’s broad tariff policies. In recent oral arguments, justices expressed doubt about the government’s stance, raising tough questions that included both conservative and liberal perspectives.
Historically, Trump was the first president to use the IEEPA to impose tariffs, which had been challenged in lower courts but remained in place during the appeals process. Meanwhile, companies have felt the financial impact. Importers had paid nearly $90 billion under these tariffs as of late September, according to U.S. Customs and Border Protection.
Costco’s Chief Financial Officer, Gary Millerchip, highlighted that a significant portion of the company’s sales comes from imported goods. Notably, about 8% of U.S. sales are from products imported from China. Despite facing increased costs from tariffs, Costco chose not to raise prices on essential items like fresh fruits to protect its customers.
In a recent statement, Millerchip mentioned that Costco is actively working with suppliers to navigate these challenges. They are looking to shift production locations and consolidate purchasing globally, which could help reduce overall costs. By the end of October, the government had collected $205 billion in tariffs, illustrating the substantial financial burden these measures have created for businesses.
With its recent lawsuit, Costco joins a growing list of companies, including Revlon and Kawasaki, seeking refunds for tariffs. This trend shows a significant pushback against government tariffs as businesses navigate a complicated economic landscape. The outcome of this case could set important precedents for companies facing similar situations in the future.
